Diesel Common Rail Injector Valve Assembly Nut Removal Disassembling Tools for F00RJ02246

Needle valve is a fine-tuning valve, the valve plug is a needle shape, mainly used to regulate the gas flow. The fine-tuning valve requires the opening of the valve port to gradually increase, and the maximum continuous fine adjustment from closing to opening. Needle plug can achieve this function. Needle plug is generally made of hardened steel long needle, and the seat is made of soft materials such as tin and copper. The seal between the needle and the seat is achieved by the tight fit of its cone. The taper of the valve needle has 1: 50 and 60 taper angles, and the cone surface should be finely ground. The seal between the stem and the seat is achieved by bellows.

Nanjing Keyuan Intelligent Technology Group Co., LTDThis paper mainly introduces some special design of needle valve electric actuator, which is mainly applied to natural gas exploitation equipment in remote areas. In view of the limited power supply conditions of the field duty equipment, 24V DC power supply is adopted, and efficient brushless DC motor is used to provide products with large torque and low power consumption, and then electric on-off valve is realized. For the special working conditions of the gas tree, the Modbus interface, electronic permission, handwheel permission, interface sealing, automatic plugging and other special designs are added. External use of standard Modbus interface and wireless communication module connection, to achieve remote valve control, saving labor costs, especially for some low-production Wells and intermittent Wells, has a good user experience.
